Not really Space related.. except that Einstein's work is space related but goodluck.

There are no tricks, just pure logic, so good luck and don't give up.

Background: Albert Einstein wrote this riddle early during the 20th century.
He said that 98% of the world population would not be able to solve it. Are you ?

Does the street start on the left or right? That is to say, does the Norwegian live n the left-most or right-most house? Otherwise, this puzzle is unsolvable.

It's not a concern, because all other houses are written as "next to", or "in the centre", that means you have no other option left.. than that they are each next to eachother.. not on the other side of the street.

And since the general IQ is 100.. and they have to adjust it often to 100 since the general population is becoming more smart.. so maybe your students are the a lot "smarter" generation or einstein was too young to be that smart (or maybe it wasn't einstein who invented it after all).. But the theory I love most.. we don't know.. so we just twist the things the way we all like to see it
